The article presents the results of a field study of the daily dynamics of the content of nitrogen compounds in the river. Reasonable near Razumnoe, the spring of the "Korsun Icon of the Mother of God" and a pond in the tract Kurginovskoe in the village. Chagrovka. The data on the content of nitrites, nitrates and ammonium nitrogen in the selected water bodies of the Belgorod region are analyzed. The analysis of the daily dynamics of nitrogen compounds is presented. During the observation period, the minimum concentrations of pollutants were observed in the spring water: nitrates - 2,68 mg / l, nitrites - 0,06 mg / l, ammonium salts - 0,38 mg / l. The average content of pollutants in the river. Reasonable: nitrates - 4,02 mg / l (0,01 MAC), nitrites - 0,16 mg / l (2 MACs), ammonium - 0,38 mg / l (0,76 MAC); in the pond: nitrates - 3,17 mg / l (0,13 MPC), nitrites - 0,28 mg / l (3,5 MPC), ammonium - 0,38 mg / l (0,76 MAC). A moderate daily dynamics of nitrate concentrations (amplitude of oscillations of 20-26 %) and insignificant daily dynamics of ammonium and nitrite compounds (3-13 %) are shown.
